Venturi Oxygen Stripping(Trademark) as a Ballast Water Treatment to Prevent Aquatic Invasions and Ship Corrosion
Abstract
One of the most influential mechanisms for the introduction of aquatic nuisance species is transport in ship ballast waters. Although several ballast tank treatments to prevent transport of aquatic or organisms appear promising, all existing approaches will result in significant costs to the shipping industry. The implementation of ballast water treatment measures would be hastened by providing the shipping industry with economic incentives for doing so. Our previous work suggests that deoxygenation may be such a treatment with benefit for ship owners by reducing corrosion, while simultaneously limiting the number of aquatic organisms surviving transport in ballast tanks. Our current investigations are providing the critical information required to evaluate the efficacy and feasibility of deoxygenation as a ballast water treatment to prevent aquatic invasions and tank corrosion. These results will ultimately lead to a fall-scale shipboard evaluation of deoxygenation as a cost-saving ballast water treatment.
